    Question How to read CAS EEPROM to program new chinese key remote ?

    Hello from France,

    One of my remote was stolen and I still have only one OEM remote keyfob for my BMW 745I e65 2004. I bought 2 new blank Chinese remotes with 7945 chip on aliexpress but the problem is that I bought a AK90+ programmer but it can only program a OEM new key and not the 7945 chip then it is useless. I bought another programmer , the HITAG2 but when I read my key, the security code is wrong then It can't read the data.

    Then last solution is to read the CAS EEPROM and load it into the HITAG2 to add a new key, but I don't know which software is able to do it , anyone can help me ?

    I tried to read EEPROM from CAS with BMW-Scanner 2.0.1 but I have error message "False start! Please remove key from the lock and try again"

    Thanks,

    Why not just buy a new key from BMW and avoid all the hassle? I'll never understand why people go through so much extra effort and problems just to save a couple bucks.

    New Chinese remote is 14$. Instead of 260$ for new bmw one. Because new remote have clean button I wanted to replace 2 remotes then it is better to do it by myself instead of pay 520$.

    Yes it is only because of the price that I want to do it myself, if I had lot of money I would have pay two new remotes of course... But if you can send me 500$, i will be happy to do what you say and going at my BMW dealer to buy two new remotes ^^
